Fukushima USA? Dangerous radioactive leaks and cracked foundations go unpunished at American nuclear power plants

Safety has taken a back seat to cost-cutting at most of the nation’s nuclear power plants, sparking fears that America could be facing its own Fukushima disaster.

An investigation by the Associated Press has revealed federal regulators are repeatedly weakening – or simply failing to impose – strict rules.
Officials at the U.S. Nuclear Regulatory Commission have frequently decided that original regulations were too strict, arguing that safety margins could be eased without peril.. . . . .

About spent nuclear fuel storage :

U.S. official says Yucca nuclear dump not an option 

(Reuters) – A controversial Nevada site is not an option for storing toxic waste from nuclear power plants, a senior U.S. official said, dismissing Republican efforts to revive the Bush-era plan.

“We do not see Yucca Mountain as a solution here,” U.S. Deputy Energy Secretary Daniel Poneman said on the sidelines of a major international meeting to strengthen global nuclear safety after Japan’s Fukushima atomic crisis.

“It is time to turn the page and try to find a better set of solutions,” he told Reuters in an interview on Monday.

The world has struggled with what to do about nuclear waste for decades, but Japan’s nuclear disaster three months ago brought fresh attention to the dilemma as much of the waste is now stored in pools next to reactors. . . .

NOTE: Nebraska nuke plants have plenty of spent fuel rods on site that need constant cooling. It is misleading when the energy co. says the plant is ‘shut down’ etc. – as if it is safe from flood waters.

More than 80% of the Japanese people distrust anything their government says about Fukushima.

TVA’s nuclear expansion plans carry great safety risk, costs

Japan has three reactors at Fukushima in a state of meltdown, pouring radiation into the air and ocean.Fort Calhoun, a nuclear power plant in Nebraska, was flooded by the Missouri River earlier this month and has experienced loss of power for the cooling of fuel rods. Three reactors at Browns Ferry narrowly missed an F5 tornado and lost outside sources of power for weeks.

You would think that these warnings would be enough for sane people to back off from production of new nuclear reactors. But what is TVA doing? Completing one new reactor at Watts Bar; getting ready to launch a $7 billion plan to build new reactors at Bellefonte and to take an old reactor there out of mothballs and spruce it up to go; contracting with Babcock & Wilcox to purchase four new mini-reactors for East Tennessee.

Project Flood nuclear ‘alert’: Obama, Red Cross declare emergencies

Project Flood 2011 and tornados meet two nuclear stations

Two United States nuclear power plants are on alert and President Obama has declared emergencies in Nebraska’s counties where the two nuclear stations are both experiencing “unusual events.” The official emergency declarations apply to both counties where the nuclear facilities are threatened with flood waters. Red Cross closed its emergency shelter at Fort Calhoun, home of one of the nuclear facilities, and is now referring and transitioning evacuees to other shelters. Red Cross is due to assess Fort Calhoun when conditions permit. . . .  (more)

Britain’s nuclear timebomb: Doomed £6bn plan to dispose of plutonium waste

One month after the Japanese tsunami, the world’s biggest reserve of plutonium waste is reaching crisis point. It was meant to be reprocessed and sold – but now no nation will take it. So where is this vast stockpile? Not Fukushima, but Sellafield, Cumbria

By Steve Connor

The nuclear crisis in Japan threatens a carefully choreographed UK Government plan to tackle the world’s biggest mountain of plutonium waste stored at the Sellafield site in Cumbria.  . . . (more)

MOX Battle: Mixed Oxide Nuclear Fuel Raises Safety Questions

One of the troubled Fukushima Daiichi reactors contains a blend of uranium and plutonium fuel that may soon find use in the U.S. Does it pose more risks than standard uranium fuel?

By John Matson

. . . reactor No. 3 at Fukushima Daiichi, one of the units that has experienced severe problems in the past two weeks, has one characteristic that differentiates it from its neighboring reactors and from any operating reactor in the U.S. Among the hundreds of standard nuclear fuel assemblies in its core, which rely on the splitting of uranium atoms to release energy, are some that contain a mix of uranium and plutonium. This so-called mixed oxide, or MOX, fuel was loaded into Fukushima Daiichi reactor No. 3 in 2010 and has found use in several other countries’ power plants as well. And a big-budget U.S. government project is scheduled to begin producing MOX for domestic utilities in 2016. . . (more)

Experts Differ Over U.S. MOX Fuel Plan

Debate persists among experts over a U.S. plan to convert 34 metric tons of excess weapons plutonium to nuclear power plant fuel at a $5 billion facility under construction in South Carolina . . .

. . . Due to the South Carolina MOX plant’s expense, “it’s certainly not something you’d think you could make money off,” Alvarez said. “I kind of see it as a nuclear equivalent to a bridge to nowhere.”

“The [Energy Department] still can’t find a utility that’s willing to take this stuff,” he added. . . (more)

Greenpeace declares evacuation zone at Atomic Energy Agency HQ

14 04 2011

Vienna – Greenpeace activists created a symbolic evacuation zone in front of the International Atomic Energy Agency (IAEA) headquarters in Vienna today, demanding that representatives of countries attending its safety committee meeting start moving towards a global phase out of nuclear energy.

The activists created the evacuation zone around a steaming cooling tower symbolizing nuclear power plants and unfurled a banner with the words ‘Exclude Nuclear power from our future’ during the final session of the IAEA’s Convention on Nuclear Safety (CNS), which comes just days after the Japanese government upgraded the Fukushima Daiichi nuclear crisis to the same level as Chernobyl (1). . .  (more)

Nuclear Regulatory Commission Skews Safety Reports Says Union of Concerned Scientists

12 04 2011

Several years ago the Nuclear Regulatory Commission started a research program known as the “State of the Art Reactor Consequence Analyses,” or SOARCA, which I discussed in a post on April 6. SOARCA’s mission is to assess the consequences of “severe accident scenarios” at nuclear power plants that might release radioactivity into the environment.

UCS has long been concerned that the NRC imposed constraints on the SOARCA program that would significantly skew its results to ensure an outcome suggesting the public has little to fear from severe nuclear plant accidents. . .

Japan Dithers, Lies About Radiation Levels

30 03 2011

From the Sydney Morning Herald:

UN atomic watchdog raises alarm over Japan evacuations

By Shingo Ito

The UN atomic watchdog said Wednesday radiation in a village outside the evacuation zone around a stricken Japanese nuclear plant was above safe levels, urging that Japan reassess the situation.

In its first such call, the International Atomic Energy Agency added its voice to that of Greenpeace in warning over radioactivity in Iitate village, where the government has already told residents not to drink tap water.

Japan has struggled to contain its nuclear emergency since a 14-metre (45-foot) tsunami hit the Fukushima plant after a huge quake on March 11, with radioactive substances entering the air, sea and foodstuffs from the region.

Iitate village is 40 kilometres (25 miles) northwest of the crisis-hit plant — outside both the government-imposed 20 kilometre exclusion zone and the 30-kilometre “stay indoors” zone.

“The first assessment indicates that one of the IAEA operational criteria for evacuation is exceeded in Iitate village,” the IAEA’s head of nuclear safety and security, Denis Flory, told reporters in Vienna on Wednesday.

The watchdog advised Japanese authorities to “carefully assess the situation and they have indicated that it is already under assessment,” Flory said.

But he added the IAEA, which does not have the mandate to order national authorities to act, was not calling for a general widening of the exclusion zone. . . .   (more)
